txhais ntawm cov nyhuv piezoelectric
Piezoelectric lub cev yog polarized los ntawm kev siv dag zog sab nraud, uas ua rau cov nqi sib txuas nrog cov paib tiv thaiv pom tshwm ntawm ob xaus ntawm lub cev piezoelectric. Lub txim uas tau ntwm yog ib qho sib npaug rau sab nraud cov tshuab quab yuam. Qhov tshwm sim no hu ua qhov zoo piezoelectric effect. Lub cev hluav taws xob tau deformed los ntawm hluav taws xob sab nraud, thiab nws cov deformation yog sib npaug rau qhov sib zog ntawm cov hluav taws xob sab nraud. Qhov tshwm sim no yog hu ua qhov cuam tshuam piezoelectric effect. Ib qho khoom siv nrog cov nyhuv zoo piezoelectric yuav tsum tau muaj qhov cuam tshuam piezoelectric effect, thiab rov ua haujlwm. Qhov zoo thiab tsis zoo piezoelectric cuam tshuam yog suav sau ua ke piezoelectric teebmeem. Seb tus siv lead ua muaj lub zog piezoelectric yog txiav txim siab los ntawm kev sib xyaw ntawm cov qauv siv lead ua.
